I secound this. Take a LONG look at whats going on in your area with other businesses too. My area we have alot of AUTO shops closing down. Alot of mechanics are out of jobs. Because ppl dont want to even spend money to get their car fixed. Yes their vehicle running right. I have had ppl say no to new tires when their tires are balding Or even close to slicks. Unsafe ball joints. #1 reason they say they just dont have the money... There is a local side shop I know that is down to one tech dosent have the work flow to have other ppl there. Note he had over 6 techs.Take a good look at the economy right now and really think if you want to get into a business deals with a product that has no real need. I mean yea car audio and tint is fun but who is paying for stuff right now ? If i were you i would go down to the college and take a few business classes before thinking about opening a business.
